OK, I know its embarrassing but the sensors were there all along, having read the reply referring to swivel sensor ring ring I realised I was looking on the axle body ( due to a diagram I had seen on another forum) when I should have been looking at the hub top, Anyway after this eureka moment I have followed all the cables to make sure everything was OK and the sensors were seated correctly. Coming to the main Valve block I then found the main electrical connector was unplugged and had been all along. After a 20min struggle and removing the ABS pump to get access the plug was back on. A quick test drive and still the warning lights are on although now in a more orderly fashion.
Ign on , both ABS and Traction control light come on
5 seconds and both go off then ABS comes back on.
Drive vehicle over 5mph and ABS light does not go out plus Traction Control light comes back on.
I have run the diagnostic sequence and still get the same code as before of 2.3 , this I have been told is not a valid code. I checked several times and cannot get anything different, always 2.3
I have tested the brakes very aggressively and they are working fine, I cannot get the car to skid so believe the abs is working. The 1st time after reconnecting the valve block plug when moving off there was a judder as though the ABS or traction control is suddenly working on its own, I felt it to be coming from the valve block, after this quick burst of activity all went to normal but with the warning lights still on.
Anyone got any ideas how i can progress to diagnose the problem? I would like to confirm the valve block is ok, is there a test procedure.
